Application filed December My invention relates to new and useful improvements in insecticide dusters for use in exterminating insects and fungus growths on plants and other vegetation'.

An object of my invention is to produce a duster which will thoroughly mix the dif ferent chemicals used therein, by imparting thereto a whirling movement, thus breaking up any lumps which may have been caused by dampness or packing.

Another object is to adapt my improved duster to be easily carried upon the back of an operator, the operating partsbeing in convenient positionsfor the manipulations of the same.

vA still further object of my invention is l to provide a cluster which may be operated by either hand for thel convenienceV of lefthanded persons, or in case oneV hand should become tired. l

' With the above and other'objects in view which will appear as the description proceeds, my invention consists in the novel features herein set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

Referring to the drawings,

Fig. 1 is a side elevation of my improved duster, showing in dotted lines, the movement of the operating lever and bellows.

'Fig'. 2 is a sectional view taken on. line 2-2 of Fig. l.

Fig. 3 is a sectional view takenvon line 3-3 of Fig. 2.

Fig. 4; is Va sectional view taken `on line H of Fig. 2. Y

Figs. 5 and 6 are detail views of the baille used in creating a vortex in the container.

Fig. 7 is an enlarged fragmentary view of the discharge pipe.

Fig. 8 is a view showing my improved duster in place on the backV of an operator.

Fig. 9 isa modification showingthe use of a plurality of outlets, which allows the handle or lever to be used oneither side by simply changing the position of the spraying tube. f

In the drawings, l1 represents a metal frame or support, which is bent at one end to conform with the shape of the small of the ybackrof a person operating the device,

as shown at 2, Fig. 2. At the other end I provide bellows 3 of any suitable kind, which are rigidly secured to the frame 1 by means of a band 4 preferably riveted thereto. 5 The inner end of said bellows is pivotally secured at 5 to a substantially U-shaped rock-V ing member 6, which preferably consists of a piece of pipe7 bent in the proper form, and pivotally mounted transversely of the frame 1, in the apertures 7 of said frame.

the otherv end of the bellows V3, I provide another rocking member 8, which is mounted in the same manner as the`U-shaped pipe 6, and which supports the 'outerr end of the bellows.

At the lower extremity of one of'theupright portions of the U-shaped pipe 6, I employ a removable lug 9, which isprovided F with two apertures 10 and 11. The aperture 10 lits over the upright portion of theI pipe 6, and is held inplace by agset screw 12, while the other'aperture 11fis adapted to receive the bent end 13 of a lever 14, said lever being held in place by a cotterpin15.

The lever 14 preferably consistsof a metal rod bent at right angles at one end as before mentioned, the main portion being curved, as clearly shown in Fig. 2, to bring the handle 16 transversely infront of `the oli-"m Y erator. l

At the end 2 of -the frame 1, I providea cylindrical dustvcontainer 17 ,having a cone shaped bottom 18, secured inside ythe walls of said container. `,The container is braced near its upper extremity by a metal strip 19 which extends from the bellows 3, and at; its lower extremity byva substantially V-shaped strip. 20 secured to the frame 1. M

The bellows 3 are connected to the con- (""l tainer 17 by a conduit 21, which passes through the lowerr portion of the cylindrical wall and into the conical bottom 18,ltheend of said conduit inside the container being provided with a screen vnipple 22, which prevents anyoff the dust in the container from backing up into the conduit or bellows.

Atapproximatelythe central portionl of the container 17, I provide a vertically extending discharge pipe l23, its upper' extremity havingfa baffle arrangementr 24, asA clearly shown in Figs. 3 andl 7,v which breaks' ico 40 i The complete duster is then secured to the'y `27, which ycreates a vortex as described. YThe dust, still in this whirling movement,

"any lumps of lchemicals that might be thrown up in the vortex, before allowing the dust to enter said pipe 23. The lower extremity of said discharge pipe is bentl approximately at right angles as at 25, and extends horizontally through the wall of the container at an angle, as shown in Figs. 2 and 3, where it is rigidly secured, the portion extending through `said wall being adapted to receive a spiaying tube 26, preferably of a flexible metallic structure.

Just below the top, inside the container 17 I provide a baille 27 which consists of a plurality of alternating angularlv disposed blades 28, preferably stamped out of galvanized iron and soldered together as shown in Figs. 3, 5 and 6. TheV baille is provided with an aperture 29 which engages the vertical portion of the discharge pipe 23, said baffle being supported by a rib 30, on the inner wall of the container 17.

The object of this baille V27, is to impart a whirling movement to the chemical or dust as it is blown up from the bottom of the container 17, against the top of lsaine and into the discharge pipe 28, as clearly shown by the arrows in Fig. 3.

The top consists of a plate 31 of suitable material, provided with a washer or gasket; 32, which renders the device air tight, said plate 31 being securedto the container -17 by means of a clamp 33, which grips the headV 34 on the upper extremity of the container,

and is tightened by a set screw 35 engaging the plate 31.

The operation of the device is as follows The container 17 is filled, preferably up to the rib 30 with the chemical or dust ii member 25 havin two outlets 36 and 37. The object of this form is that it enables the user to change the lever 14 and lug 9, over to the other side when one hand becomes tired, and operate the spraying tube with the right hand, by simply disconnecting the tube 26 from the outlet 36 and placing it on the outlet 37, closing the former outlet with a threaded cap 88.

This form might also prove vadvantageous to a left handed person.

YVhile I have described a bellows of any kind, for supplying air to the container 17, I prefer vand have'shown a double acting bellows which provide a constant air pressure from the under side of the baffle 27, and insures a continuous whirling movement of the dust particles.

It lmight also be stated that while I have shown and described bellows, a tank containing compressed air may be used with equally vas good effect. l

From the foregoing, invention m ay be clearly understood without further description, and in closing I may say that numerous changes may be made in Vit-'he details of construction without departing from the spirit of the invention as disclosed in the following claims. i y
